Description

Technical Field

[0001] The utility model relates to the technical field of vehicle bodies of engineering machinery, in particular to a skylight lock structure of an engineering machinery cab. Background Art

[0002] As a key component of construction machinery cabs, the functionality and performance of skylights are gaining increasing attention from users. With the increasing demand for ergonomics in construction machinery, skylight design has become a key indicator of overall cab quality. However, traditional skylight designs often make it difficult to precisely control the opening angle of skylights in construction machinery cabs, causing significant inconvenience for users.

[0003] When the cab remains closed for extended periods, harmful substances released from the interior materials, such as volatile organic compounds (VOCs) like benzene and formaldehyde, gradually accumulate in the air. These harmful gases not only affect air quality but also pose a potential threat to human health. Furthermore, while fully opening the sunroof in hot summer weather increases ventilation, it also exposes the driver directly to strong sunlight. In cold winter weather, the cabin temperature can drop rapidly, causing discomfort and even health risks. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a skylight lock structure for the cab of engineering machinery. In view of the problem that the current skylight can only be opened at a small angle, the utility model achieves the purpose of air circulation in the vehicle through optimized design.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A sunroof lock structure for an engineering machinery cab includes a sunroof, a sunroof lock, a sunroof lock block, and a top cover. The sunroof lock is fixed on the sunroof. The sunroof lock includes a fixed rotating seat and a turning handle. The middle part of the turning handle is located in the fixed rotating seat. The turning handle includes a clamping portion. A clamping slot is provided in the middle part of the sunroof lock block. The clamping portion is movably connected to the lower edge of the sunroof lock block and the clamping slot respectively. The sunroof lock block is fixed on the top cover.

[0007] Preferably, the sunroof lock is fixed to the sunroof via a sunroof lock bracket, and the sunroof lock bracket is U-shaped.

[0008] Preferably, the skylight lock block is fixed to the top cover via a skylight lock block bracket.

[0009] Preferably, the longitudinal section of the slot is rectangular, and the four corners are chamfered.

[0010] Preferably, the handle includes a grip portion.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] Simple structure, easy to implement, and meet diverse needs: This solution can adapt to different operating conditions and personal preferences by flexibly adjusting the opening angle of the sunroof, meeting users' diverse needs for the cab environment. It also occupies a small space, has a simple structure, is easy to install and maintain, and reduces manufacturing costs and usage complexity. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0020] like Figure 1-5The sunroof lock structure of a construction machinery cab shown in the figure includes a sunroof 1, a sunroof lock bracket 2, a sunroof lock 3, a sunroof lock block 4, a sunroof lock block bracket 5, a top cover 6, and a card slot 7. The sunroof lock 3 is fixed to the sunroof 1 through the sunroof lock bracket 2. The sunroof lock bracket 2 is U-shaped, and the U-shaped side wall of the sunroof lock bracket 2 is fixed to the sunroof 1. The sunroof lock 3 includes a fixed rotating seat 31 and a rotating handle 32. The top of the fixed rotating seat 31 is fixed to the U-shaped bottom wall of the sunroof lock bracket 2 by bolts. The middle part of the rotating handle 32 is located in the fixed rotating seat 31 and can rotate left and right. The rotating handle 32 includes a hand grip 321 and a clamping portion 322. The hand grip 321 is located on the left side of the fixed rotating seat 31. The hand grip 321 is used to push and pull the sunroof 1 up and down, and is also used to rotate the clamping portion 322 to make the sunroof 1 in a closed state and a small-angle open state. The clamping portion 322 is located on the right side of the fixed rotating seat 31. The sunroof lock block 4 is fixed to the top cover 6 through the sunroof lock block bracket 5. A clamping slot 41 is provided in the middle of the sunroof lock block 4. The longitudinal section of the clamping slot 41 is rectangular, and the four corners are chamfered. When the clamping portion 322 is located at the lower edge of the sunroof lock block 4, the sunroof 1 is in a closed state; when 322 is located in the clamping slot 41 of the sunroof lock block 4, the sunroof 1 is in a small-angle open state.

[0021] Working principle:

[0022] When the sunroof is closed, the latch engages the bottom edge of the sunroof lock block, ensuring a tight closure. When opening the sunroof at a small angle, the latch moves to the central slot in the sunroof lock block, promoting air circulation while preventing excessive opening. For a wider opening angle, the latch completely disengages from the sunroof lock block, allowing the sunroof to open freely. This design, with its simple structure and compact size, not only effectively improves in-vehicle air quality but also meets diverse needs, such as a wider field of view, enhancing driving comfort and safety.

[0023] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
